Here's a new set of photos of the Honda CR-Z Mugen RR competition study that made its debut alongside the more production ready CR-Z Mugen Concept at the beginning of July in the Moving Motor Show area at Goodwood Festival of Speed.

While the CR-Z Mugen was designed and built by "MUGEN EURO" based in the UK, the more hardcore RR model is the work of the firm's Japanese division.

For some automakers such as Porsche and BMW, a black edition version of one of their cars means everything is finished in black, for others including Mazda and Holden, it's more like a secondary trim color.

Honda's CR-Z "α Black Label" ("Alpha Black Label") can be classed in the second category as the Japanese market only edition of the hybrid sports coupe justifies its name only through the color choices inside and to a lesser extent, the darker shade of the alloy wheels.

A few weeks ago at the Goodwood Festival of Speed, Honda unveiled a concept study of the hybrid CR-Z prepared by Mugen’s European division.

The fettled CR-Z retained the regular model’s mechanical hardware including the IMA electric motor and the 1.5-liter gasoline engine, but the upgraded internals and the addition of a supercharger increased its performance by more than 50% over the normal model, to 200+ horsepower and 215 Nm (158.6 lb/ft).

The almost production ready Honda Mugen CR-Z Concept wasn’t the only product from the Japanese automaker’s in-house tuning company to debut at the Goodwood Festival of Speed.

Along with the street-legal CR-Z Concept Mugen also brought along a competition version bearing the ‘RR’ moniker. The conceptual Mugen CR-Z RR sports a more dynamic aero package comprising of bespoke parts such as the wider front and rear bumpers with air-vents, side skirts, a rear diffuser and larger rear wing.

One of the biggest problems most see with Honda’s CR-Z hybrid sport hatch is the lack of a performance version. That may change soon enough as Mugen’s European division is readying a “highly-tuned” version of the CR-Z that it claims will deliver “Type R-like” performance. The faster and more powerful CR-Z Mugen prototype is being developed as a joint project between Honda UK and Mugen Euro, and it will make its world debut at the Goodwood Festival of Speed this July.

“This will be one quick hybrid,” said Martin Moll, Head of Marketing for Honda UK. “With more torque, more power and MUGEN’s experience of working with Honda cars, we’re expecting great things. It promises to show how hybrid cars can be even more exciting to drive.”

Honda said that the CR-Z MUGEN prototype will feature modifications to both the 1.5-litre i-VTEC petrol engine and the Honda IMA system to boost power and torque, adding that these changes may also result in greater mpg and lower CO2 emissions during some conditions. Final power, torque and fuel economy figures are not yet known.
